1. Evolution Lineup | Five stages of the main unit, each bigger | PET EVOLUTION | progression
Simulator progression thumbnail. A left-to-right evolution lineup on five raised platforms across a classic green Roblox baseplate, each stage clearly bigger and shinier than the last: (1) a tiny grey pup, (2) a fluffy blue wolf cub, (3) a glowing purple wolf, (4) a winged golden wolf, (5) a colossal rainbow cosmic wolf with a starry mane. A glowing gold upgrade arrow sits between every pair. A Roblox player avatar stands beside the final stage with a shocked, amazed face, arms spread. Bright blue sky, strong rim light, high contrast. Add bold white text with a thick black outline at the top: "PET EVOLUTION".

2. Cheap vs Rich | Hard split, sad cheap side vs gleaming rich side | $1 VS $1,000,000 | versus
Split-screen thumbnail with a hard vertical divide. LEFT, grey and gloomy: a rusty little go-kart with a flat tyre and a sad Roblox noob avatar beside a wooden "$1" sign. RIGHT, bright and gleaming: a chrome-and-gold supercar with glowing blue underlights, a confident Roblox avatar in sunglasses leaning on it, coins and sparkles in the air, and a gold "$1,000,000" price tag. Strong colour contrast between the halves. Add bold white outlined text across the top: "$1 VS $1,000,000 CAR".

3. Giant Builder | Colossal player placing a tiny building | YOUR TINY TOWN | scale
Tycoon thumbnail. A COLOSSAL Roblox player avatar, 50x taller than the town, kneels at the edge of a miniature town with a huge excited grin, placing a tiny house onto the street with two fingers. Ant-sized Roblox townsfolk wave up at him. An invented town hall with a fictional flag (teal with a gold anchor emblem, no real-world flags) flies on its roof; it is not a real building. Low camera angle at street level looking up at the giant. Bright blue sky, green Roblox baseplate, playful scale contrast. Add bold white outlined text at the top: "YOUR TINY TOWN".

4. Raid Incoming | Cozy base at dusk, enemies over the hill | RAID INCOMING! | threat
Tense action thumbnail at dusk with a blue-purple sky. The player's cozy Roblox-style base in the foreground with warm window lights and a red alarm siren spinning on a watchtower. In the background a horde of cartoon zombie Roblox avatars pours over a hill. In the foreground a Roblox player avatar looks back over his shoulder with a panicked face. Red emergency light accents, strong contrast. Add a red banner at the top with bold white text "RAID INCOMING!" and a small countdown badge "0:10".
